Cardiff City have sacked one member of staff and are set to discipline another amid claims that their team to play Crystal Palace last weekend was leaked to the London club.
The action has been taken after the allegations emerged on yesterday morning.
Cardiff manager Ole Gunnar Solskjaer earlier dismissed any suggestion of involvement by any member of the Cardiff squad.
It is understood that Premier League officials have requested information on Cardiff's case.
It is thought the person sacked has been dismissed for gross misconduct following an internal enquiry at the club.
Palace sporting director Iain Moody worked for Cardiff until he took up a post at Palace in November.
It has been reported that Cardiff believe Moody might have used his contacts at the Welsh club, or close to Cardiff, to find out which players would start against Palace.
Moody denies the allegations.
